1

Cervical spine's important job

Supports our head
Directs our vision
Protects the spinal cord (connection or our brain to the rest of the body)

2

Anterior

Front

3

Posterior

Back

4

Vertebra

Bones that make up the spine

5

How many bones make up the spine?

24

6

Vertebra stacked on top of one another are called

the spinal column

7

The body's main upright support is the

spinal column

8

How many vertebra make up the cervical spine?

7. Often referred to as c1 - c7

9

What does the bottom of the skull connect to?

c1 or atlas

10

Which direction does the cervical spine curve?

Slightly inward

11

Where does the cervical spine end?

Where c7 joins the top of the thoracic spine

12

What sits on top of c1 or atlas?

The base of the skull

13

What forms a hole through the center of the atlas?

Two thick boney arches

14

Why is the opening the largest in the atlas

Because the spinal cord is wider where it first exits the brain

15

Where does the atlas sit?

On top of the c2 also referred to as the axis

16

What is the boney nob on top of the axis called?

the dens. it points up and fits through a hole in the atlas

17

What gives the neck its ability to turn to the left and right?

The special connection between the atlas and axis

18

What is the main part of each cervical vertebra?

A round block of bone called the vertebral body

19

What attaches to the back of the vertebral body?

A bone ring formed by to pedicles that connect to the back of the vertebral body and two lamina that join the pedicles to complete the ring

20

What do the vertebra form when stacked on top of one another?

A hollow tube that surrounds the spinal cord. The inside of this tube is called the spinal canal

21

What do the bone rings provide?

A protective roof that protects the spinal cord

22

What projects posteriorly from the same point where the two lamina bones join together at the back of the spine?

Boney projections called spinous processes. These are what you feel when you rub your fingers up and down the back of your spine

23

What are the two boney knobs that point out to the side from the vertebra?

Transverse Processes

24

What passes through the transverse processes of the cervical spine and is unique to the cervical spine?

Transverse foramen

25

What does the transverse foramen provide?

A passageway for arteries that run up each side of the neck to supply the back of the brain with blood

26

What are between each set of vertebra?

two joints called facet joints

27

What covers the surface of the facet joints?

Articular cartilage, a smooth rubbery material that covers the ends of most joints. It allows the ends of the bones to move together smoothly with minimal friction.

28

What is formed when vertebra are stacked on top of one another?

Neural foramen

29

What leaves through the neural foramen?

A nerve root leaves through this opening. One on the left and one on the right

30

What does the spinal cord travel through?

The spinal cord travels through the spinal canal

31

Where do the nerve roots from the cervical spine go?

The upper extremities, upper body and certain organs

32

What are ligaments?

Strong connective tissues that connect bones to other bones

33

Anterior Longitudinal Ligament

Runs lengthwise down the front of the vertebral bodies

34

Posterior Longitudinal Ligament

Attaches on the back of the vertebral bodies

35

Ligamentum Flavum

a long elastic band that connects to the front surface of each of the lamina bones

36

What are facet joints surrounded by

a joint capsule that is made up of ligaments

37

Intervertebral disc

A special structure in the spine that sits between each pair of vertebra

38

What two parts make up the intervertebral disc?

the nucleus pulposus annulus fibrosis

39

What is the nucleus pulposus

A spongy material that sits in the middle of the intervertebral disc and provides most of the shock absorption for the spine

40

What is the annulus fibrosis?

A series of strong ligamentous rings that surround the pulposus annulus fibrosis that attach to the vertebra above and below the intervertebral disc

41

What is a spinal segment?

Two vertebra separated by an intervertebral disc, two nerve roots, two small facet joints that link each level of the spinal column

42

How does the cervical spine bend and rotate?

The working together of the facet joints and the intervertebral disc. The facet joints slide while the intervertebral disc works like a flexible disc between the two vertebra

43

What is the cervical spine?

A complex machine with an important job to do.

44

How can you understand how problems in the neck can cause pain and disfunction?

By understanding the structure and function
